Abstract
The paper presents the MTF (Modulation Transfer Function) evaluation of diffraction-limited images captured by smaller relative aperture imaging systems, and also the restored images with Wiener Filtering method and iterative blind algorithm. The influence of noise in the image and not-exactly PSF (Point Spread Function) in the process of reconstruction are discussed.
